Application filed November To all whom it may concern Be it known that I, ANTHONY Nansen, a citizen oi the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented new and useful li'nprcvenients in Cue Chalkers, of which the following is a specification.

It is my object to provide novel and etficient means for chalking the tips of pool or billiard cues.

A further object of my invention is to provide a device of this kind which is durable and inexpensive to manufacture.

My invention also includes various novel features of construction which will be more fully pointed out in the following specification and claims.

Referring to the accompanying drawi g.., which illustrate the best form of my device at present known to me, Figure 1 is a plan View of my improved cue chalker in its normal position on the guides; Fig. 2 is a side elevation of the same; Fig. 3 is central vertical section of the device in operation, a fragmentary portion oi the one being shown in position for applying the chalk to the tip; Fig. 4 is a detail elevation of one of the spring holders and Figs. 5 and 6 are side and end views, respectively, of the spring detent which fits into the holder shown in Fig. 4.

My improved chalker is adapted to be secured to the under surface of the overhanging side rail on a pool or billiard table by means of a pair of. brackets 10 which are performed at 11 to receive screws. A pair of guides 12, extending between and rigidly connected to the brackets 1.0, are provided to support the ohalkcr proper. lhese guides are ci rculu r inv cross section and pass through suitable 'ier'torations in downnuirdly projecting ends 13 ot a frame 14. T he frame 14 slidal'ile longitudinally on the guides 12 and is formed with upwardly projecting liiearings 15 and a central aperture 16 in which a pair of guide pulleys 17 are mounted.

Pieces of cue chalk 18 are carried in a pair of containers 19 having bell-mouth open ends 20. The containers 19 are formed with hubs 19 which are rigidly secured to opposite ends of the supporting spindle 21. This spindle is revoluble in the bearings 15 and carries a spring housing 22 between said bearings. A coiled spring 23, enclosed in the housing .22 around the spindle 21 is se- 21, 1925.

cured at its ends to a pair of holders 24 (shown in detail in Fig. 4). These holders consist of a ring 25, which-fits inside of the housing 22, and a pair of bars 26, united at their ends to said ring and curved outward to straddle the spindle 21. One of the holders 24 is secured by a. pin 27 to the housing 22 and spindle 21, and. the other holder,

which is secured to the opposite end of the spring 23, is held against rotation by a de tent 28. (See Figs. 5 and 6.) This detent comprises a collar 29 which fits over the spindle 21 and is formed with a pair of lugs 30. The detent- 28 fits between and engages the bars 26 of the adjacent spring holder 24, and also extends into the adjacent bearings 15, suitable keyways being cut in said bearing to receive the lugs 30. spring 23 is thus adapted to resiliently hold the spindle 21, and the containers 19, against rotation in the bearing 15.

A chain 31, consisting of a series of links fastened end to end by suitable ball joints, is wound on and secured at one end to a drum 32 on the housing 22. The chain 31 passes downward between the guide pulleys 17 and its lower extremity is fastened by a pin 33 to the guides 12. The pulleys 17 are tilted so that the chain 31 in passing tangentially from said pulleys will pass tangentially to the drum 32.

Operation.

as described above, on a pool or billiard table or it may be placed on any suitable support near the table. The frame 14, carrying the chalk containers and operating mechanism is normally held near the middle of the guides 12 (in the position shown in Figs. 1 and 2) by the action of the spring23 which winds the chain 31 on the drum 32.

To chalk the tip of a cue, the one is placed in horizontal position with its tip inserted in the bell-mouth end 20 of the container at either end of the spindle 21, (see Fig. 3) the cue being indicated at 34. The one is now thrust toward the chalker. This thrust slides the frame 14 longitudinally on the guides 12 against the action of the spring 23 and actuates the chain 31 to rotate the containers 19 and chalk upon the tip of the cue. The frame 14, carrying the chalk containers and rotating mechanism, thus slides to the end of the guides 12 and is stopped by the bracket 10. The one 34 is now removed al- The 1. A cue chalkercomprising,a support, a-

frame slidable on said support, a chalk container revolubly mounted on said frame, re silient means for holding said container against rotation onsaid frame and means for rotating said container against the action of said resilient means when said frame slides on said support;

2. A one chalker comprising, a support, a frame slidably mounted onsaid support, a chalk container revolubly mounted on said frame, a spring adapted to restrain rotation of said container, and means. for rotating.
